a Safety Precautions
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.
Do not make any changes or modifications to the equipment
unless otherwise specified in the instructions. If such changes or
modifications should be made, you could be required to stop
operation of the equipment.
This equipment has been tested and found to comply with the
limits for class B digital device, pursuant to part 15 of the FCC
Rules. hse limits are designed to provide reasonable protection
nst hamful interference in a residential installation. This
ment generates, uses and can radiate radio frequency
ergy and, if not installed and used in accordance with the
instuctions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of
the following measures:
a Safety Precautions
• Do not look at the sun or a bright light source
through the lens or camera. Doing so could result
in loss of vision. Looking at the sun directly through
the lens is especially hazardous.
• Whether it is attached to the camera or not, do
not leave the lens under the sun without the
lens cap attached. This is to prevent the lens from
concentrating the sun’s rays, which could cause a
fire.
Handling Cautions
• If the lens is taken from a cold environment in
a warm one, condensation may develop on the
lens surface and internal parts. To preven
condensation in this case, first put the lens into an
airtight plastic bag before taking it from a cold to
warm environment. Then take out the lens after it
has warmed gradually. Do the same when taking
the lens from a warm environment into a cold one.
• Do not leave the lens in excessive heat such as in
a car in direct sunlight. High temperatures can
cause the lens to malfunction.
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Consult the dealer or an experienced radio/TV technician for
help.
This Class B digital apparatus complies with Canadian ICES-003.

• After detaching the lens, place the lens with the
rear end up to prevent the lens surface and
electrical contacts from getting scratched.
• If the contacts get soiled, scratched, or have
fingerprints on them, corrosion or faulty
connections can result. The camera and ens

from rain, snow, and dust.
Attach and align the hood to the hood mount on
the front of the lens, and turn the hood as shown
by the arrow to secure it.
The hood can be reverse-mounted on the lens
for storage.
If you autofocus outside the set focusing distance
range, the lens may stop focusing at the start of
the focusing range; however, this is not a
malfunction. Press the shutter release button
halfway again.
• Part of the picture may be blocked if the hood is
not attached properly.
• When attaching or detaching the hood, grasp
the base of the hood to turn it. To prevent
deformation, do not grasp the rim of the hood to
turn it.
• Remove the hood when using the macro flash.

Normal Photography
While looking through the viewfinder, move the
camera forward or back to find the point of
focus.
4. Touch up the focus.
Turn the focusing ring for fine focusing.
The lens can be used as a telephoto lens for
normal photography.
Closeup Photography
Close-up photos (minimum focusing distance of
0.48m) up to 1x (life-size) magnification are
possible. The minimum focusing distance is the
distance from the subject to the film plane. The
distance from the front of the lens to the subject
(working distance) is about 0.25m.
Since macro shots have a very shallow depth of
fieldfocus carefully to obtain proper sharpness.
Imae quality deteriorates near the minimum
aperture opening due to diffraction.
• The magnification refers to the ratio between the
subject’s size and the corresponding image size
on the focal plane. On the distance index, it is
indicated as 1:x.
• To prevent camera shake, using a Remote
Switch (both sold separately) and tripod is
recommended.
When focusing, you can give priority to framing
or to magnification.
[Framing Priority]
While looking through the viewfinder and framing
the subject, focus with the AF or MF mode.
[Magnification Priority]
1. Set the lens’ focus mode switch to MF.
2. Set the magnification.
• To check the depth of field, press the camera’s
depth-of-field preview button.
While referring to the magnification scale on
the lens, turn the focusing ring to the desired
magnification.

With TTL metering, AE (autoexposure) is
possible at all focusing distances. Just set the
desired picture-taking mode, then check the
shutter speed and aperture before taking the
picture.
• The correct exposure for a close-up shot largely
depends on the subject. Therefore, it is
recommended to take several shots of the same
ject at different exposures.
• Whn taking close-up shots, it is recommended
to use aperture-priority AE (Av) or Manual (M)
picture-taking modes, because depth of field
and exposure are easy to adjust in those
modes.
Magnification and Effective f-number
The aperture displayed by the camera assum
that the focus is set to infinity. The actua
aperture (effective f-number) becomes drke
(effective f-number increases) at closer focusing
distances (magnification increases). This does
not cause exposure problems for normal picture-
taking. However, for closeup photography, you
cannot ignore the change in the effective f-
number.
When you use a handheld exposure meter to
set the exposure, you must take into account
the exposure factor shown in the following
table.

9. Macro Flash
(Sold Separately)
The Canon Macro Ring Lite MR-14EX or the
Macro Twin Lite MT-24EX enables fully automatic
macro flash photography up to 1x magnification
in E-TTL autoflash mode.
For normal photography, remove the Macro Lite
Adapter, because it may create a dark
circumference.
Install the Macro Lite Adapter 72C (sold
separately) on the filter mounting thread on the
front of the lens for macro flash photography.
• For information on operating the Canon Macro
Ring Lite MR-14EX or the Macro Twin Lite MT-
24EX, refer to the individual instruction booklets.
• Using aperture-priority AE (Av) or Manual (M) is
reommended.

10. Using the Tripod Mount
Adjusting the Revolving Mount
You can loosen the orientation lock-knob on the tripod mount to allow it to rotate as needed to fit a
particular camera model for switching between vertical and horizontal positions.
Detaching
First remove the lens from the camera and then remove the tripod mount from the lens as shown
below. To attach the tripod mount, reverse the procedure.
Loosen the orientation
locking knob.
Rotate the tripod mount and
align the mounting indicator
on the tripod mount with the
one on the lens.
Slide off the tripod collar
away from the rear of the
lens.
If the foot of the tripod mount overlaps the switch, loosen the orientation locking knob on the tripod mount to
move the foot.

• First attach the Extender to the lens, thn attaclens to the camera. Detach it from the
camera in the reverse order. If you attah the lens to the camera first, misoperation may
occur.
• With the EF1.4X II Extender attached, autofocusing is enabled from 0.8 m/2.6 ft. to infinity.
Autofocus mode cannot be used to take pictures closer than 0.8 m/2.6 ft. due to the relation
with the effective F value, so use manual focusing.
• If you use an Extender on the lens mounted on a EOS A2/A2E/5, set the exposure
compensation to -1/2 stop for the EF1.4X ll or -1 stop for the EF2X ll.
• Only one Extender can be attached to the lens and camera.

enables close-up photography.
Magnification will be 1.48× – 0.36×.
• Close-up Lens 250D cannot be attached
